GTP ButterOn 85D
Rigid Thixotropic
P
Description GTP ButterOn 85D consists of two thin liquids, Part A (cream) and Part B (green). After mixing, GTP ButterOn 85D immediately thickens to a buttery non -sag paste, which forms a high strength rigid bond. GTP ButterOn 85D is especially well suited for forming rigid parts and molds. When fully cured, GTP ButterOn 85D forms a rigid “fiberglass like” polymer that is easily sanded or machined into final form. GTP ButterOn 85D can also be used as a rigid mother mold back up for flexible molding compounds. GTP ButterOn 85D can be used with expanded polystyrene foam as an adhesive or “hard” coating. The Thixotropic (self thickening) nature of GTP ButterOn 85D allows for easy application to difficult overhead and vertical surfaces. GTP ButterOn 85D contains no solvents or fumes thereby avoiding fire and worker health hazards in contained work environments
Application All surfaces to be coated with GTP ButterOn 85D should be coated with silicone mold r e-lease “Parfilm” (available through Industrial Polymers) to prevent unwanted bonding. Parts to be coated must be absolutely dry. Fabric or chopped fiber can be used to enhance the physical properties of the cured material. Application and curing of finished parts should be done in a dry environment to prevent any unwanted surfacing bubbling. All parts are fully cured in 24 hours @ 7 2° F before removing clamps and trimming access adhesive. Elevated temperatures will accelerate cure time, and cooler temperature will slow down curing.
Mix Ratio Condition liquids to 72° F, remove container lids and stir carefully stir component A and component B separately. Carefully measure out equal parts of component A (cream beige) and component B (green) in separate cont ainer. Do not mix more than one quart of finished material per batch. To insure proper mixing and adequate working time. Pour all of comp onent B into component A and mix by hand with flat spatula. Carefully scrape sides down and bottom of container to insure all of both components are included in the mixture. Mixture will change color to a lighter green and thicken to a creamy paste and beco me slightly warm to touch. Apply thickened mixture to surface.

Shelf Life GTP ButterOn 85D 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 85D is available in convenient 2-quart, 2-gallon and 10-gallon kits. GTP ButterOn 85D has a non-hazardous rating for shipping.
