MIXING INSTRUCTIONS:
- Premix INSULCAST 961 in its original container. The filler in INSULCAST 961 will float to the surface and form a light crust which readily re-disperses.
- Weigh out the required amount of INSULCAST 961.
- Measure into the INSULCAST 961 the proper amount of INSULCURE (see chart).
- Mix thoroughly, scraping both the sides and bottom of the container.
- Pour into unit or cavity.
CURING AGENT RATIO CHART:
100:11-12 with INSULCURE 9 - Fast cure and small castings
100:23-25 with INSULCURE 44 - Larger castings
100:12-18 with INSULCURE 13 - Fastest cure
CURE SCHEDULE:
INSULCURE 9: Overnight at room temperature (24 hrs. @25°C)
INSULCURE 44: Overnight at room temperature (24 hrs. @25°C)
INSULCURE 13: 2-3 hrs. @25°C.
STORAGE REQUIREMENTS:
This product contains lightweight glass microballoons which have a tendency to float toward the top of the container during shipment and storage. The product must be re-mixed well prior to use. Store material in a cool dry place.
LIMITATIONS:
Do not pre-heat material during use or before material has gelled. Pre-heating will lower the viscosity and cause excessive phase separation of the glass microballoons. Some phase separation is normal as the material gels but will be more noticable in the black version.
IMPORTANT:
The following supersedes any provision in your company's forms, letters and papers. AMERICAN SAFETY TECHNOLOGIES, INC. makes NO WARRANTY, WHETHER EXPRESSED OR IMPLIED, INCLUDING WARRANTIES of MERCHANTABILITY OR of FITNESS FOR A PARTICULAR PURPOSE FOR THIS PRODUCT. No statements or recommendations contained in the product literature are to be construed as inducements to infringe any relevant patent, now or thereafter in existence. UNDER NO CIRCUMSTANCES SHALL AMERICAN SAFETY TECHNOLOGIES, INC. BE LIABLE FOR INCIDENTAL, CONSEQUENTIAL OR OTHER DAMAGES FROM ALLEGED NEGLIGENCE, BREACH of WARRANTY, STRICT LIABILITY OR ANY OTHER THEORY, ARISING OUT of THE USE OR HANDLING of THIS PRODUCT. The sole liability of AMERICAN SAFETY TECHNOLOGIES, INC. for any claims arising out of the manufacture, use or sale of its products shall be to refund the buyer's purchase price, provided such products have been demonstrated in AMERICAN SAFETY TECHNOLOGIES, INC. sole opinion, to justify such refund.
HEALTH CAUTION:
Avoid breathing possible fumes, mists and vapors which can cause severe respiratory damage. Use of NIOSH approved breathing apparatus is required for more than minimal exposure. Always work in areas with adequate ventilation to allow dissipation of polyamine and other chemical fumes, and where applicable, solvent fumes. Use of goggles, protective garments, rubber gloves, protective cream is required. If material gets into eyes, flush thoroughly with clear water for twenty (20) minutes; then seek medical treatment. Avoid skin contact. Material can cause contact dermatitis. Always wash exposed areas immediately, using warm water and soap, followed by rinsing with clean water. Observe all safety precautions. It is important when using solvent based materials or solvents to keep away from open flame or ignition source.
