Resin modifiers have gained wide acceptance as a unique form of commercial building waterproofing sealant. Advances in adhesion technology have produced phenolic resins through the synthesis of polymers at the molecular level. These resins belong to a group of low-cost adhesives — the lowest in the industry. Phenolic resins come in one- or two-part liquid, emulsion or powder, and can be used as a base or modifier resin in an adhesive formulation. Often it is exposed to another element to induce a reaction that produces adhesion.
Resin-based formulations adhere to many types of surfaces. They have remarkable resistance to water and climate changes. They can tolerate a high level of temperature exposure and even resist intense heat and flame. As a part of a commercial building waterproofing solution, phenolic resins are reliable, strong, and quite inexpensive compared to other types of sealant products.
Siloxanes are 100% active powder formulations that possess excellent flame retardant properties. Polymerized siloxanes are a mixture of silicones with organic and inorganic polymers. They are available in either passive or reactive grades. Siloxane powders are very useful to combat mold infestation of surfaces, preventing the release of mold spores and stop mold growth. With siloxane powders, commercial building waterproofing projects have a higher abrasion resistance.
Siloxane-based sealants are preferred for exterior commercial building waterproofing because they are easy to handle and their bonding strength to almost any surface type is higher than any other sealants.
