Formula Application
Recommended Dosage
The suggested addition level for RT7105A ranges from 0.05% to 5.0%.
Addition Guidelines
It is recommended to dilute the product prior to use, then add it slowly while dispersing at high speed. To achieve optimal high-gloss results, it is advisable to add the product before the emulsion; the dosage may be adjusted based on the final product’s performance requirements.
Compatibility
RT7105A is specifically designed for a wide range of coating systems; it demonstrates exceptional performance in water-based formulations and is broadly applicable to acrylic, alkyd, epoxy, and polyurethane systems. It is particularly well-suited for use in high-gloss, high-hardness water-based topcoats and industrial coatings.
This product exhibits excellent compatibility with both cellulose-based and alkali-swellable thickeners, allowing for a flexible combination. It can be utilized either independently as a sole thickener or in conjunction with other thickening systems to flexibly optimize rheological properties and application performance.
RT7105A Typical Applications
RT7105A enhances mid-shear viscosity, improves application feel, minimizes splashing and sagging, and boosts system stability.
RT7105A enhances sag resistance, resulting in a more uniform, refined spray finish while reducing application defects.
RT7105A improves brushability, maintains high transparency, and enhances film leveling and surface texture.

FAQ About RT7105A
Suitable. Its operation method is relatively user-friendly. As long as the addition sequence and stirring conditions are controlled properly, there is generally no problem of poor dispersion.
This may cause the system to become overly viscous or less fluid, thereby affecting the construction feel. For instance, the brushing process may become “draggy”.
RT7105A does not contain organotin and belongs to environmentally friendly additives.
We can discuss favorable quotations based on purchasing volume.
We can optimize material matching schemes to cut comprehensive production costs reasonably.
