GTP ButterOn 40
Urethane Elastomer
P
Description GTP ButterOn 40 is a two component urethane elastomer that is specifically formulated as brush on molding compound. After mixing, GTP ButterOn 40 thickens to a creamy butte r-able gel that can easily be brushed on to vertical or overhead surfaces without sagging or running. In 24 -hours GTP ButterOn 40 cures to a tough rubber mold and is ready for use. Some features of GTP ButterOn 40 include, good grease and oil resistance, easy 1 to 1 mix by volume, good adhesion between coats and it is insensitive to inhibition. It is also tough, with high tear resistance, is color coded for mix indication and has long mold storage life.
Application GTP ButterOn 40 is mixed 1 part of component A to 1 part of component B by volume, and has a working life of 10 to 15 minutes @ 72° F. W armer temperatures will decrease working life where as colder temperatures will increase working life. GTP ButterOn 40 can also be mixed by weight: 100 parts of component A to 96 parts of component B.
GTP ButterOn 40 is fully cured in 24 hours @ 72° F. Colder curing temperatures will lengthen cure times. Warmer temperatures will greatly reduce working and curing times. For clean-up use methyl ethyl ketone (M.E.K.), acetone or mineral spirits.
Mix Ratio Component A and component B are supplied in 1 to 5 gallon containers. Component B should be thoroughly mixed before using. Component A does not need mixing. Carefully measure out equal portions of component A and component B by volume in separate co ntainers. Mix small batches by hand with a spatula. Larger batches should be mixed using a “Jiffy mixer” and electric drill. While mixing material carefully scrape down sides and bo t-tom of container. Mixture gradually thickens over a 1 to 2 minute period to a creamy butte r-able consistency.

Shelf Life GTP ButterOn 40 is shipped from the factory in sealed containers. The containers should be stored in a cool dry area that is protected from direct sunlight and moisture. Storage temperatures should not exceed 80° F. The shelf life of factory sealed containers stored under these conditions is six months. Containers that have been opened should be resealed immediately after material has been removed in order to prevent solvent evaporation.
Packaging GTP ButterOn 40 is available in convenient 2-quart, 2-gallon, 10-gallon, 60-gallon and 100gallon kits. GTP ButterOn 40 has a non-hazardous rating for shipping.
