6. ACCIDENTAL RELEASE MEASURES
Containment/Clean up: Observe all personal protection equipment recommendations described in Sections 5 and 8.
Wipe up or scrape up and contain for salvage or disposal. Clean area as appropriate since
spilled materials, even in small quantities, may present a slip hazard. Final cleaning may
require use of steam, solvents or detergents. Dispose of saturated absorbant or cleaning
materials appropriately, since spontaneous heating may occur. Local, state and federal laws
and regulations may apply to releases and disposal of this material, as well as those materials
and items employed in the cleanup of releases. You will need to determine which federal,
state and local laws and regulations are applicable. Sections 13 and 15 of this MSDS provide
information regarding certain federal and state requirements.
Note: See section 8 for Personal Protective Equipment for Spills. Call (989) 496-5900, if additional information is
required.
7. HANDLING AND STORAGE
Use with adequate ventilation. Product evolves flammable methyl alcohol when exposed to water or humid air. Provide
ventilation during use to control exposure within Section 8 guidelines or use air-supplied or self-contained breathing
apparatus. Product evolves t-butyl alcohol when exposed to water or humid air. Provide ventilation during use to control
exposure guidelines or use air-supplied or self-contained breathing apparatus. Avoid eye contact. Avoid breathing vapor.
Keep container closed. Do not take internally.
Use reasonable care and store away from oxidizing materials. Keep container closed and store away from water or
moisture.
8. EXPOSURE CONTROLS / PERSONAL PROTECTION

comments.
3087-39-6 t-Butyl titanate See t-butyl alcohol comments.
18395-30-7 Isobutyl trimethoxysilane See methyl alcohol comments.
T-butyl alcohol forms on contact with water or humid air. Provide adequate ventilation to control exposures within
guidelines of OSHA PEL (final rule): TWA 100 ppm, 300 mg/m3 and ACGIH TLV: TWA 100 ppm. Methyl alcohol

General Ventilation: Recommended.
Personal Protective Equipment for Routine Handling
Eyes: Use proper protection - safety glasses as a minimum.
Skin: Washing at mealtime and end of shift is adequate.
Suitable Gloves: No special protection needed.
Inhalation: Use respiratory protection unless adequate local exhaust ventilation is provided or exposure
assessment demonstrates that exposures are within recommended exposure guidelines. IH
personnel can assist in judging the adequacy of existing engineering controls.
Suitable Respirator: General and local exhaust ventilation is recommended to maintain vapor exposures below
recommended limits. Where concentrations are above recommended limits or are unknown,
appropriate respiratory protection should be worn. Follow OSHA respirator regulations (29
CFR 1910.134) and use NIOSH/MSHA approved respirators.
Personal Protective Equipment for Spills
Eyes: Use full face respirator.
Skin: Washing at mealtime and end of shift is adequate.
Inhalation/Suitable Respiratory protection recommended. Follow OSHA Respirator Regulations (29 CFR
Respirator: 1910.134) and use NIOSH/MHSA approved respirators. Protection provided by air purifying
respirators against exposure to any hazardous chemical is limited. Use a positive pressure air
supplied respirator if there is any potential for uncontrolled release, exposure levels are
unknown, or any other circumstance where air purifying respirators may not provide adequate
protection.
Precautionary Measures: Avoid eye contact. Avoid breathing vapor. Keep container closed. Do not take internally.
Use reasonable care.
Comments: Product evolves flammable methyl alcohol when exposed to water or humid air. Provide
ventilation during use to control exposure within Section 8 guidelines or use air-supplied or
self-contained breathing apparatus. Product evolves t-butyl alcohol when exposed to water
or humid air. Provide ventilation during use to control exposure guidelines or use air-supplied
or self-contained breathing apparatus.
Note: These precautions are for room temperature handling. Use at elevated temperature or aerosol/spray applications may require
added precautions.

11. TOXICOLOGICAL INFORMATION
Component Toxicology Information
This material contains methyltrimethoxysilane (MTMS). MTMS was evaluated in a combined repeated-dose toxicity study
that included screening tests for reproductive and developmental toxicity (OECD 422). Sprague-Dawley rats were treated
(oral route, corn oil as carrier) daily at dose levels of 0, 50, 250, and 1000 mg MTMS/kg body weight. Test article effects
on organ weight were limited to increased liver weight for both males and females in the top two dose levels.
Histomorphological findings included increased hepatocellular hypertrophy (both sexes) and increased periportal
vacuolation (females only) in the top two dose levels. Thymus weight was decreased in males in the top two dose groups.
The thymus appeared normal histomorphologically. Other test article related histomorphological changes included
increased incidence of thyroid follicular cell hyperplasia/hypertrophy and severity in males and females in the top two
dose levels. There was also an increased incidence of hyperplasia/hypertrophy, apoptosis, and lymphocytic infiltration in
the zona reticularis of the adrenal glands in high-dose females and acanthocytosis in high-dose males and females.
Clinical pathology evaluations demonstrated a marked prolongation in prothrombin time for males in the top two dose
levels. Marked elevation in blood platelet count was observed in both males and females at the high dose. Serum total
protein was elevated in high-dose males and in females from the top two dose levels. Serum total cholesterol was
elevated in females from the top two dose levels. There were no test article related effects on any of the reproductive and
developmental endpoints. Because this study is considered to be a screening of repeated-dose and
reproductive/developmental toxicity, the results do not provide sufficient information needed to interpret potential
relevance to human health and are not indicative of a specific toxicity. This type of study is commonly used as a screening
study to determine whether further testing should be conducted. Also, this study was conducted via the oral route of
exposure, which is not a typical route of exposure for either manufacturing or end use applications of MTMS. A
longer-term study by a more relevant route of exposure (inhalation) is being conducted to understand these preliminary
findings.
A 14-day whole-body inhalation toxicity study of methyltrimethoxysilane (MTMS) in Sprague-Dawley rats (5 males / 5
females per group) was conducted in preparation of dose level selection for a 90-day repeated dose toxicity study.

Sprague-Dawley rats were treated six hours per day for 14 consecutive days to exposure levels of 0 (control), 400, 800,
4000 and 8000 ppm MTMS. Signs of excessive urine staining and bloody urine were present following the first or second
day of exposure in animals from 4000 and 8000 ppm exposure groups. All animals from the 8000 ppm exposure group
and three animals from the 4000 ppm group were euthanized prior to scheduled terminal sacrifice. The primary gross
pathology findings in these animals consisted of urinary bladder and kidney effects. Urinary bladder findings included
dilation, calculi, abnormal contents and color. Kidney findings included mild to moderate dilation. Additional findings in
females from the 4000 ppm exposure group included enlarged adrenal glands, small thymus and a mild gaseous
intestinal tract. The relevance of these findings to human health is unknown. Additional testing (90-day repeated dose) is
being conducted to better understand these findings.
