Description of Addovate EM:
Addovate EM is a non-ionic emulsifier for the production of PUR ester flexible slabstock foam.
Chemical Composition of Addovate EM:
Polyetherpolyol.
Applications of Addovate EM:
PUR ester flexible slabstock foam for "textile" applications Addovate EM is used as an emulsifier for water, catalyst(s) (e. g. Addocat DB / 117) and the polyester polyol.
Addovate EM can also improve the open-cell structure of foams, especially in combination with Addovate TX.
The recommended dosage is 1.0 - 4.0 pphp.
The following sequence of adding the individual components had proven effective when manufacturing the activator batch: water, catalyst(s), Addovate EM, Addovate TX.
A clear, homogeneous mixture is obtained.
In the production of low odor PUR ester flexible slabstock foam Addovate EM is used as emulsifier in combination with Addovate 3240 and small amounts of silicone stabilizers.
Warning:
When mixing with other emulsifiers or additives, it is advisable to carry out laboratory tests for compatibility, as incompatibilities may cause defects in the cellular structure.
Packaging of Addovate EM:
• Metal drums, contents 200 kg
• Plastic containers, contents 1000 kg
Storage conditions of Addovate EM:
Addovate EM is to be stored in a cool and dry place.
When Addovate EM is stored in firmly closed original containers at 10 to 30 °C, a shelf-life of 12 months from manufacturing date can be expected.
The containers should be resealed tightly after use to prevent contamination by impurities and exposure to moisture.
Handling of Addovate EM:
Consult the safety data sheet for relevant safety data & references as well as possibly necessary warning labels.
Application Notes of Addovate EM:
PUR ester flexible slabstock foam for "textile" applications:
In the production of PUR ester flexible slabstock foam Addovate EM is used as an emulsifier for water, catalyst(s) (e. g. Addocat 101, Addocat PV, Addocat 117) and the polyester polyol. Addovate EM also improves the open-cell structure of foams. Addovate EM is usually used in combination with Addovate TX.
The recommended amount is between 1.0 and 4.0 parts by weight Addovate EM to 100 parts by weight polyester polyol.
The following sequence of adding the individual components had proven effective when manufacturing the activator batch: water, catalyst(s), Addovate EM, Addovate TX. A clear, homogeneous mixture is obtained.
Low odor PUR ester flexible slabstock foam:
In the production of low odor PUR ester flexible slabstock foam Addovate EM is used as emulsifier / stabilizer in combination with Addovate 3240 and small amounts of silicone stabilizers.
