IMPREPOX 1000

The parts to be bonded or filled must be clean, completely dry and free of dust; if possible, roughen them slightly.
Mix thoroughly the two dosed components, in the ratio (by weight) of 4 : 1 (A : B), using small quantities of product in order to avoid waste from too fast curing (mass effect). For a good job, usually 250-300 grams (8-11 oz per mixing) at a time are sufficient per single catalysis. The mix has a workable time of 20/30 minutes at 20°C/68°F, the time will be longer at lower rooms temperature and shorter at higher room temperature. Grinding can be done after 24 hours at room temperature (20°C/68°F), or it is possible to warm the slab to higher temperature
in order to shorten drying time:
Substrate temperature Full curing time
20°C (68°F) 24 hours
30°C (86°F) 12 hours
40°C (104°F) 6 hours
50°C (122°F) 4 hours
60°C (140°F) 3 hours
Finishing (smoothing) can be run after 6-7 hours (at 20°C/68°F) from jointing, after 14-16 hours (at 20°C/68°F) can be sanded. Complete polymerisation will be after 7 days from applications. Do not apply at temperatures below 10°C/50°F.

Suggestion for use and recommendations:

• - Avoid to use the mastic at temperature below 10°C (50°F) because drying process could not be complete.
• - Epoxy resins are sensible to humidity because could change reaction times, it is advised not to apply the product in situation of high humidity.
• - Never catalyze the total quantity of the mastic at one time in order to avoid “mass effect” because the mastic will dry quickly.
• - Do not use hardener in different ratio than indicated on the tin or in the present bulletin; it will prejudice catalysis time and could never dry, or change the color of catalyzed product.
• - Do not use the coloring paste in quantity more than 5% as it could prejudice the adhesion.
• - Part A and Part B should be taken only with different paddles/spatulas.
• - Adhesive already thickened or in gel phase could no longer be worked.
• - Tools can be cleaned with nitro solvent.
• - Keep lid well closed and store product in a cool and ventilated place
• - Avoid contaminating part A with part B.
• Before use read the recommendations printed on the label and always carry out a preliminary test.
