Core Problems It Solves

WTA-245T wetting agent is a high-efficiency silicone wetting addtitives with well-balanced performance. It precisely solves these below application problems for customers in the coatings, inks, and cleaning fields:

1. Solves the problem of substrate wetting issues such as poor coating, pinholes, and fisheyes.

In water-based systems, water has a high surface tension (approximately 72 dyne/cm), making it difficult to spread on low surface energy substrates (such as plastics, oily metals, old paint layers, and release paper).

Application problems: After painting, shrinkage, exposed substrate, or round pits resembling "fisheyes" are observed. 

Application solutions: It rapidly reduces the system surface tension to below 22 dyne/cm. This means it forces the liquid to spread on difficult surfaces, effectively resolving the issuer of pinholes and improving coating efficiency.

2. Solves the problem of poor adhesion and difficulty in recoating in multi-layer coatings. 

While ordinary silicone oil-based additives can increase smoothness, they often form a wax-like film on the surface, making it difficult to apply the second coat or causing it to peel off easily after drying.

Application problems: In wood coatings or leather finishing, after applying the primer, the topcoat doesn't adhere well or the interlayer adhesion is insufficient.

Application solutions: It doesn't improve smoothness and doesn't affect interlayer adhesion. This solves the biggest concern for customers who require adhesion more, making it ideal as a primer wetting agent or in coating processes requiring multiple color layers.

3. Solves the problems of foaming and stable foaming. 

Many high-efficiency wetting agents (such as traditional polyether-modified siloxanes) generate a large amount of persistent foam while reducing surface tension, leading to pinholes and bubbles in the coating film.

Application problems: High-speed stirring or spraying generates a large amount of foam; adding too much defoamer can cause pinholes.

Application solutions: It has low-foaming stability. While providing excellent wetting power, it does not reduce reliance on defoamers like conventional surfactants.

4. Solves the problems of cost control and compatibility

Cost-effectiveness: Wetting agent's effective content is 100% (pure substance), and the addition amount is extremely low (typically 0.1-0.5%). This can significantly reduce formulation costs for customers who is requiring mass production.

Versatility: It can be used in both water-based and solvent-based systems and has good compatibility with resins.

FAQ

Q1: What is a wetting agent? 

A wetting agent reduces liquid surface tension by adding very small amounts (typically 0.1-2%). It can allow coatings, inks, leather, and industrial cleaning solutions to spread smoothly and penetrate deeply.

Q2: What are the core characteristics of a wetting agent?

WTA-245T Silicone Wetting Additive is suitable for both water and oil applications, prevents cratering, reduces surface tension, and has good compatibility. It can perfectly replace EVONIK's TEGO-245.

Q3: Can WTA-245T really be used in both water-based and oil-based (solvent-based) systems?

Yes. This type of wetting agent has extremely wide compatibility. Whether it's water-based architectural coatings and wood coatings, or metal industrial coatings based on organic solvents (such as butyl acetate and xylene), it remains stable and effectively reduces surface tension.

Q4: What are the sample packing and bulk packing?

Sample packing: 80ml in one bottle. Or depending on your requirements.

Product Packaging: 25KG, 50KG Plastic Bucket

Q5: What precautions should I take when storing the wetting agent?

Unopened at room temperature, the product has a shelf life of 24 months from the date of production.

Q6: What is the recommended dosage of the wetting agent?

0.1 - 1.0% on total formulation is recommended.
