Product Description

 

 

Self-crosslinking Waterborne acrylic resin WL-TC106

 

 

When high performance, such as excellent chemical and solvent resistance, is needed in a one-component coating, the self-crosslinking acrylics are preferred. WL-TC106 describes a new self-crosslinking waterborne acrylic resin, designed for use in wood coating and metal coating applications. it can be formulated into wood finishes,metal coatings that are one-component, high performance and low VOC,low MFFT, high film gloss, and good anti-adhesion property.

 

I. INTRODUCTION:

1. WL-TC106 is free of heavy metals, phthalates, formaldehyde, and APEOs. It is a green product and complies with worldwide regulations about health and environment, the VOC content of this product is less than 1.0 wt%.

2. Provide low minimum film formation temperature (MFFT) and good anti-adhesion property. it also provides excellent heat resistance and high film gloss.

3. Good adhesions on glass, woods, ceramics, R/C surfaces, and metals. It can provide a film with good harness when the coating is dried under room temperature.

4. Is manufactured with a proprietary self-crosslinking technology, which offers properties of excellent water whitening resistance, alkali resistance, and early cracking resistance.

5. Has good leveling and low foaming properties, which allows them to be applied by spraying or brushing process onto different substrates.

6. Can be easily thickened by regular thickeners, such as HEUR, HASE, and cellulosic thickeners. It is advisable to start with a lower level of thickener (maybe half or 1/3 the initial level according to your experience), let the formulation stabilize overnight, and then adjust the final viscosity.

 

 

 

II. Main characteristics
