The SK Pouch, a Greener Container

As a general manufacturer of adhesives and sealing products, Sharp Chemical Industry develops new products to meet the needs of industry and the home.
One of those products is the environmentally friendly SK Pouch.

Conventional containers for sealants and adhesives must be thrown away after use and because they are rigid, occupy a great deal of space after disposal, a major environmental problem for both construction sites and the home.
The SK Pouch decreases the volume of waste by 90 percent and is made with 80 percent less material than typical containers, making this product a greener alternative.

Sealants, Adhesives, Corking

What is more, the SK Pouch is highly functional. Unlike conventional manual cartridge-type containers, the SK Pouch can be managed by hand or with a tool.
The original design for this container received the Good Design Award in 2001.
Neither formalin or toluene are used in the manufacture of the SK Pouch, so it is gentle on the environment and human health.

Sharp Chemical Industry has domestic and international patents pending for the SK Pouch.

Dansei Bond, a Resilient Adhesive

Almost everyone has had the experience of using an adhesive advertised as ultra-strong, only to find that the object pops back off.
No matter how strong the adhesive is, when you try to glue two objects with a different coefficient of thermal expansion, the bond will not be able to withstand shocks unless the adhesive has resiliency.

Sharp Chemical Industry’s Dansei Bond is resilient and ideal for use with materials having different coefficients of thermal expansion such as stainless steel plate and concrete.
This product is ready for use. No need to mix or combine products.

Brand Labeling

Sharp Chemical Industry will brand their adhesive and sealant containers with your company’s name. This is particularly useful during construction and remodeling projects.

Although the outside has your company’s name, the content has the same high-quality silicone, modified silicone, urethane and other tried and true products from Sharp Chemical.
This service is available for cartridges as well as the SK Pouch lineup.
Labeling can be done with colors, dimensions and other design effects to meet your company’s logo.
