Description
[Martin A Carbone, Inc, Santa Barbara, CA] A trademark for a two-part epoxy putty. Gapoxio (TM) epoxy resin contains mixed diglycidyl ethers of Bisphenol A that is mixed with an amine hardener. Fillers include clay, silica, lime and magnesia. Gapoxio (TM) has a working time of about 45 minutes after kneading equal parts of the A and B sticks. It cures in about an hour at room temperature with no shrinkage. Gapoxio (TM) has a light beige-gray color but dry pigments can be added during mixing for other variations. After cure, the solid resin can be drilled, sanded, cut or painted.
