ADCO Sister Company Expects Polysulphide Sealant Restrictions Through the Summer
June 9, 2011

Suppliers of polysulphide polymers of IG sealants continue to experience supply issues as a result of shortages coming from the Toray Thiokol production facility in Chiba, Japan, following the March earthquake.

“We are indeed aware of the supply issues,” says Michael Speicher, National Accounts Manager for ADCO Products Inc. “ADCO does not produce polysulphide in the United States but Kömmerling, our sister company in Germany, does and they indeed are affected by availability.”

According to a news release issued by Kömmerling, “With other suppliers operating close to capacity, polysulphide sealant supplies could be restricted during the busy mid-summer period and there are indications of significant price rises in the pipeline from the other polymer suppliers. Kömmerling estimates that it will be able to maintain normal supplies to existing customers during this period, but will not be able to take on additional volumes for the foreseeable future. Further price increases should be expected.”

The release further states:

“The primary PIB-based sealants used in IG production are also in a tight supply position following disruption of Japanese production. Raw material for PIB is short and escalating in price. Kömmerling predicts that it has sufficient supplies at present to meet normal high summer demand from existing customers, but prices are likely to increase. Insulating glass producers should be cautious about fixing long-term prices in this unstable situation.”
“This definitely affects customers in North America that buy from Kömmerling,” Speicher says. He adds, ““We have informed each customer personally.”
