# CP-98 Organoclay Additive to Reduce Porous Substrate Penetration | Camp-Shinning
Porous substrates such as wood, concrete, or unsealed mineral surfaces can absorb liquid components from solvent-based coatings, leading to uneven film build, poor hiding, and variable gloss. Camp-Shinning supplies **CP-98 organoclay additive** to stabilize the coating structure, helping reduce excessive penetration and improve uniform appearance.
## Why Excessive Penetration Causes Problems
– Solvent and resin absorption reduces wet film thickness
– Pigments concentrate unevenly, affecting color and hiding
– Gloss and surface feel become inconsistent
– More coating is required to achieve target coverage
## How CP-98 Helps Stabilize Coatings on Porous Surfaces
CP-98 can:
– Build low-shear structure that holds liquid components in the film
– Improve application stability on absorbent substrates
– Reduce run-in and uneven penetration patterns
– Support more consistent film build and appearance
## Typical Applications
– Wood primers and sealers
– Solvent-based coatings applied on concrete or masonry
– Protective coatings on blasted or porous substrates
– Architectural coatings needing consistent coverage on absorbent surfaces
## Best Practices for Formulators
– Optimize viscosity profile for wet film hold and leveling
– Combine with appropriate primer design for difficult substrates
– Validate penetration behavior with absorption tests
– Evaluate hiding power and gloss uniformity on target materials
## FAQ
### Can CP-98 reduce absorption on porous wood?
It can help stabilize the coating and reduce excessive liquid penetration, supporting more uniform film build.
### Does it replace a dedicated primer?
It supports coating stability, but primers are still important for sealing highly absorbent substrates.
### Will it affect flow and leveling?
CP-98 is designed to balance structure with flow; dosage and dispersion should be optimized for appearance.
### What tests can confirm penetration control?
Absorption tests, film build comparisons, hiding evaluation, and gloss uniformity checks are commonly used.
