Organoclay for Waterproofing Applications
Our premium organoclay products deliver outstanding rheology control and thixotropic performance in petroleum solvent-based waterproofing systems -- ensuring superior anti-sag, water resistance, and long-term durability.
Why Organoclay in Waterproofing?
In petroleum solvent-based waterproofing coatings and membranes, organoclay acts as a powerful rheology modifier and thixotropic agent. It prevents sagging on vertical surfaces, controls viscosity under shear, and enhances the suspension of pigments and fillers for a uniform, high-performance film.
- Excellent anti-sagging on vertical and overhead surfaces
- Stable viscosity control across temperature ranges
- Superior suspension of pigments and fillers
- Compatible with petroleum solvent-based systems
- Enhanced water and moisture barrier performance
Recommended Products
Our engineers recommend the following organoclay grades specifically optimized for petroleum solvent-based waterproofing formulations.
CP-34
High-performance organoclay with excellent gelling efficiency in petroleum solvent systems. Ideal for heavy-duty waterproofing membranes requiring strong thixotropy and anti-sag control.
- Strong thixotropic gel structure
- High compatibility with aliphatic solvents
- Excellent anti-settling performance
CP-26
Versatile organoclay grade offering balanced viscosity and gel strength. Well-suited for general-purpose waterproofing coatings and sealants in petroleum solvent bases.
- Balanced rheology and gel strength
- Smooth application and leveling
- Suitable for brush, roller, spray
CP-RL
Self-activating organoclay with reduced need for polar activators. Designed for ease of dispersion in low-polarity petroleum solvents, delivering reliable waterproofing performance.
- Easy dispersion, self-activating grade
- Low-polarity solvent compatibility
- Consistent batch-to-batch performance
Technical Guidance
Engineer's Step-by-Step Usage Guide
Follow these recommended steps from our application engineers to achieve optimal dispersion and performance of organoclay in petroleum solvent-based waterproofing systems.
-
1
High-Speed Dispersion of Organoclay in Petroleum Solvent
Add the organoclay (CP-34, CP-26, or CP-RL) to the petroleum solvent oil. Stir at high speed to achieve initial dispersion and begin building the gel network.
Cutting speed: 8-12 m/sUse sanding machine for best results -
2
Add Polar Activator (Methanol or Ethanol)
Introduce 45-60% methanol as a polar activator while continuing high-speed stirring. The activator promotes full intercalation and maximizes gel strength. If methanol is restricted or unavailable, ethanol is a suitable alternative.
Primary ActivatorMethanol -- 45-60%
Recommended for optimal activation
Alternative ActivatorEthanol
Use when methanol is not permitted

3
Add Pigment and Resin -- Grind or High-Speed Stir
Introduce pigment and resin into the mixture. Grind using a sanding machine or stir at high speed to ensure homogeneous dispersion throughout the waterproofing formulation.
Important: Solid Resin Handling
If the resin is in solid form, heat it to a liquid state before adding to the mixture. This ensures uniform blending and prevents uneven dispersion or clumping.
