1.Classification: HPMC can be divided into instant type and hot-melt type. Instant-type products disperse quickly in cold water and disappear into the water. At this time, the liquid has no viscosity, because HPMC is only dispersed in water and has no real dissolution. After about 2 minutes, the ...Read more »

Clean the back of the tile first. If the stains, floating layer and residual release powder on the back of the tiles are not cleaned up, it is easy to gather and fail to form a film after the adhesive is applied. Special reminder, the cleaned tiles can only be painted with adhesive after they are...Read more »
