KDK Chemical List of Products and Services

The "CRT-40" is a translucent, condensation-type, high-strength silicone that has low viscosity comparable to general-purpose types, making it highly effective for mixing, stirring, degassing, and pouring tasks in mold-making silicone rubber. Additionally, because the silicone is translucent, bubbles can be easily visually confirmed. During the demolding of the original model and when producing replicas, the visibility inside the silicone mold is improved, leading to higher work efficiency. 【Properties after curing】 ■ Rubber hardness (Shore A): 40 ■ Tensile strength (MPa): 4.0 ■ Tear strength (N/mm): 25 ■ Elongation (%): 450 *For more details, please refer to the PDF document or feel free to contact us.

• Formwork material

The "IS-CRN25" is a highly flexible silicone rubber with a rubber strength of 25 degrees and an elongation rate of approximately 500%. Additionally, compared to typical low-hardness, high-strength silicone, its viscosity before curing is about 2/3, which improves workability. It can be used for complex mold making that has been difficult to demold in the past, including figures, crafts, artificial rocks, and artificial wood. 【Features】 ■ Rubber strength type 25-28 degrees ■ An elongation rate of 500%, making it suitable for mold making of artificial rocks and wood ■ The curing agent is colored red to visually prevent mixing defects *For more details, please refer to the PDF document or feel free to contact us.

• Formwork material

The "IS-CRN40" is a silicone rubber for molding that, despite being a high-hardness type, possesses a low viscosity level comparable to that of general-purpose types, making it highly effective for mixing, stirring, degassing, and pouring operations. The strength after curing is approximately nine times that of standard molding types (tensile strength). The number of mold releases is several times greater compared to typical molding silicones (compared to our products), allowing for a smaller mold area even for larger quantities. 【Features】 ■ Low viscosity before curing (13-15 Pa·s) ■ Easy mixing, stirring, and pouring ■ Low viscosity similar to domestically produced general condensation types ■ Tear strength is about nine times stronger ■ The curing agent is colored green to visually prevent mixing failures *For more details, please refer to the PDF document or feel free to contact us.

• Formwork material

We offer two types of high-strength (high tear resistance) low-viscosity "molding silicone rubber series" that are easy to pour. "CRN40" has a low viscosity before curing (13-15 Pa·s), making mixing, stirring, and pouring easy. "CRN25" is a rubber hardness type of 25-28 degrees, with an elongation rate of 500%, making it suitable for molding artificial rocks and wood. Additionally, our products contain a promoter on the curing agent (catalyst) side, which minimizes thickening of the main agent due to storage, ensuring a longer shelf life. 【Features】 ■ High strength ■ Low viscosity ■ Low price *For more details, please download the PDF or feel free to contact us.

• Formwork material

We handle "Unsaturated Polyester Resin 8120X・W." 8120X is a non-wax type, while WC is a wax type. We specialize in the production of FRP molded products (such as yachts, boats, bathtubs, water tanks, and rigging tools) using hand lay-up and spray-up methods. Please feel free to contact us if you have any requests. 【Packaging】 ■20kg: Can ■225kg: Drum *For more details, please download the PDF or feel free to contact us.
