WANNATE HMDI

^{1. Specification}

^{2. Application}

^{WANNATE® HMDI (4,4’-dicyclohexyl methane diisocyanate) is a liquid cycloaliphatic diisocyanate. It is a colorless or pale yellow liquid with low viscosity and characteristic odor.}

^{Equivalent Weight ~ 214}

^{Viscosity at 25 ℃ ~ 30 mPa·S}

^{Freezing Point 25 ℃}

^{WANNATE® HMDI is the raw material for polyurethanes. Polyurethane resins based on WANNATE® HMDI have good mechanical strength. They resist abrasion and hydrolysis and retain gloss and physical properties upon weathering. A unique feature of WANNATE® HMDI is its ability to form optically clear polyurethanes when combined with suitable polyol reactants. Products based on WANNATE® HMDI may be helpful in coatings for flooring, roofing, maintenance, and textile applications, as in cast elastomers, potting and encapsulation compounds, optical products, medical products, adhesives, and sealants.}

^{3. Package(s)
20 kg/60 kg/220 kg Metal drum}

^{4. Storage / Solubility}

^{WANNATE® HMDI is sensitive to moisture and should be stored in its sealed original containers. Water or moisture in the air reacts with the product and generates pressure. If partially filled containers are stored, blanketing the liquid surface with dry nitrogen before sealing is advisable.}

^{At approx. 25 ℃, crystals will generate in WANNATE® HMDI and setting on the bottom. The product should therefore be heated to 40 ~ 50 ℃ and homogenized before use. This process also allows the use of the product which has already crystallized.}

^{5. Features
Great rebound capability
Breathable and eco-friendly
Adjustable rebound time and touch feeling
Excellent adhesion}

^{6. Shelf Life}

WANNATE® HMDI is sensitive to moisture and must be stored in a tightly sealed container. It can be stored for at least 12 months at temperatures between 0 and 30 ℃

Shenzhen Feiyang Protech Corp., Ltd. specializes in researching and producing polyaspartic polyurea resin and other new chemical products. We are recognized as a "National Special New Key Little Giant" and a "State-level High-tech Enterprise", with more than 50 polyaspartic polyurea invention patents. We also participated in the preparation of 13 industry standards for polyaspartic polyurea materials as a leading company in this field, ranking No.1 in the Chinese market.

In the coating industry, polyaspartic polyurea is used in construction machinery, automobile, containers, fan blades, marine heavy corrosion protection, and high-end industrial and commercial floor coatings. In the adhesive field, it is mainly used in sealants, stone adhesives, electronic adhesives, film circuit packaging adhesives, and other high-end applications. In the waterproofing materials sector, it is primarily used in hydroelectric dams, water parks, building waterproofing repair materials, and other areas. In the structural materials field, it is applied to curling tracks, artificial ice skating rinks, and other structural materials.

Polyaspartic polyurea is considered a high-end new material in the strategy of manufacturing power. We have broken the foreign technology monopoly and filled the domestic market gap. Due to its comprehensive characteristics of "Environmental protection, Energy saving, and Long durability", polyaspartic polyurea can contribute to the realization of genuine carbon neutrality in the coatings, adhesives, and materials industries.

Since 2012, Feiyang polyaspartic ester resin has been supplied overseas. It has been widely used to replace Bayer's current polyaspartic system in many coating companies and has been applied in anti-corrosion and waterproofing by international coating companies.
