Manufacture's Feature

Light Chemical Industries Co., Ltd. operates the company under the motto, "Creating products carefully, deeply, and promptly.”

In the chemical industry, where competition to invent new products is fierce and speed of development is required, we promote contract manufacturing by providing you with our production technology and facilities to complete your new product development and trial production studies quickly and smoothly.

We actively introduce new facilities and analytical equipment (clean rooms, microanalyzers, etc.) since our customers' newly developed products often require high quality.

We provide you the proposal-based contract manufacturing service with speedy production and cost reduction.

We are a pure-play manufacturer focused on contract manufacturing to rapidly provide you the product you requested with the utmost priority on maintaining the confidentiality of information.

Specialized Areas

We are a resin composite processing manufacturer specializing in contract manufacturing.
We trace prototypes developed by our customers to our production facilities and quickly commercialize them. Our specialty in processing is high-viscosity products (700,000 mPa-S), and we polymerize, esterify, and dehydrate polymers such as acrylic, urethane, and epoxy to produce adhesive bond, gluing agents, paint bases, coating agents, and other products.
