Mastic Tenax Liquid Straw

Mastic Tenax Liquid Straw ML.750

Low viscosity liquid mats used to bond,glue,fill and repair marbles, onyxes and stones horizontally. The hardened product is well polished and foldable. Good cold reactivity, low retention and excellent adhesion to marble and stone. Good chemical resistance. Low styrene content and excellent storage stability.

Instructions for Use

Before applying the product make sure that the material is clean, dry and free from dust. Remove from the container / jar / tin of the mastic the necessary amount of mastic you will need to use, add 2-3% of the hardener to the paste, mix vigorously and proceed to use. Never put in the mixing container mixed with the catalyst that has not been used. It should be necessary to correct the color of the mastic, use coloring dyes for polyester or metal oxides. The color is to be added before the catalyst. Add the amount needed to obtain the desired color, and then add the catalyst to get the hardening. An excess of dyeing paste or pigment powder could alter the final characteristics of the mastic.
