The Tenax Adhesives and epoxies are available in different consistencies – flowing and knife grade.
Using professional-grade epoxies, polyesters, and other bonding solutions is simple. Knowing some basic information when it comes to using mastics, epoxies, or other types of glue can be a tremendous help for you.
Epoxy is by nature polymers that contain epoxide groups. They react with a specific hardener and form a cross-link (referred to as curing). This kind of cross-link usually offers high mechanical properties, temperature, and chemical resistance. Usually, the part A (resin) has to be mixed with a specific ratio of part B (Hardener) to obtain complete curing. Typical ratios are 1:1. 2:1, 4:1 5:1.
The glue that instead is usually referred to as an epoxy (in the stone industry) is usually an unsaturated polyester resin, that in conjunction with 3% of a catalyst (usually BPO) creates a cross-link chain. These glues have usually a solvent (up to 4-5%), are faster in the curing process and usually have a weaker strength compared to epoxy systems due to the chemical reaction.
Epoxy is usually a better choice when choosing the right glue to have durable and strong bonding on different kinds of stone. Its chemical property makes epoxy a glue of choice on granite where the surface is very hard and not very porous. It is also one of the few types of glue suggested for indoor and outdoor applications.
Polyester glues can be used in all fabrication jobs for gluing or seaming when the material will only be indoor and strength is not an issue.
If cost is an issue then polyester can be cheaper then epoxy. For lamination or seams, the cost of the glue is only a fraction of the entire cost of the project, making the choice based on cost a very poor one.
