A multi-chemistry wetting platform for dry mortars, waterborne construction coatings, PCE admixtures, natural-stone epoxy impregnation and 100% solids floor systems. The grades are engineered to accelerate particle wet-out, improve additive dispersion and reduce defects such as cratering, crawling, fisheyes and dry voids.
MAKE THE LIQUID
GO WHERE IT MUST.
The supplied TDS defines the series as wetting and interfacial-tension modifiers for construction chemicals, natural-stone slab processing, epoxy coatings and dry-mix formulations.
LOWER CONTACT ANGLE.
ACCELERATE SPREAD.
Wetting agents reduce liquid surface/interfacial tension so the formulation can spread across high-energy or difficult low-energy surfaces, enter micro-pores and displace trapped air more efficiently.
Contact Angle = A Practical Wetting Indicator
Lower contact angle means greater spreading. The TDS uses dynamic contact-angle reduction on polished granite to compare silicone, fluorosilicone and fluorosurfactant behavior.
THREE ROUTES TO BETTER WETTING
1 · Surface-Tension Reduction
Lower liquid surface tension to improve initial spread across concrete, stone, mortar or coating substrates.
2 · Capillary Penetration
Low interfacial tension promotes spontaneous resin draw into dense stone micro-fissures before cure.
3 · Dynamic Leveling
Silicone and fluorosilicone chemistries reduce surface-tension gradients that can produce craters, crawling or orange peel.
Dry-Mix Wet-Out
Powder wetting technology activates with gauging water to hydrate RDP/HPMC systems more quickly and reduce clumping.

DATA
The five-grade comparison below follows the supplied Wetting Agents & Surface-Active Additives TDS.
Selection logic: lower equilibrium surface tension improves spreading potential, but final performance also depends on dynamic wetting, foam tendency, resin/water compatibility and substrate chemistry.
