760 is a sodium silicate based fibrous adhesive which is easily applied by brush or trowel (application method should be specified when ordering). Once dry, it maintains maximum adhesion and rigidity in relatively high temperature applications up to 800°F.
760 is most frequently used to bond dense, medium weight insulation materials such as calcium silicate and mineral wool, particularly where high temperatures will be present. It is recommended that a test application be done on any fibrous type of insulation if it contains a binder which might be adversely affected by the high pH of this adhesive.
For best results, both surfaces of insulation should be coated with 760 and allowed to stand open for a minimum of two minutes but not more than ten minutes prior to joining.
760 CONTAINS NO ASBESTOS, LEAD OR MERCURY COMPOUNDS.
In the dry state it is soluble in water and therefore should be suitably protected if used in an application where exposure to water will occur.
NOTE: 760 Nuclear Grade is available to comply with NRC Reg. Guide 1.36 or MIL-I-24244C(SH). This data sheet is not intended to represent exact data for 760 Nuclear Grade.
CAUTION: Do not add water to this product as that will change its physical properties and performance. No expressed or implied warranty will be offered on applications where the product has been thinned or altered.

PRECAUTIONS
Do not freeze prior to application. Stir 760 well before using. High humidity will slow curing time. Sodium silicate is a skin and eye irritant; flush with plenty of clean water if such contact occurs. Ingestion will cause discomfort; call a physician.
