Elastomeric composition

An elastomeric system comprising:

• a resin component comprising;
• a polyetherol comprising an ethylene oxide cap of from 5 to 20 parts by weight based on 100 parts by weight of said polyetherol, having a hydroxyl number of from 20 to 60 mg KOH/g, and having a nominal functionality of from 2 to 4;
• and
• a polyetheramine having an amine number of from 20 to 120 and a number average molecular weight of from 1,000 to 5,000 g/mol;
• an isocyanate component;
• a first catalyst comprising a metal selected from the group of tin, titanium, zirconium, hafnium, and combinations thereof;
• and
• a second catalyst comprising a urea that reacts with said isocyanate component to reduce emission of volatile organic compounds,
• wherein said elastomeric composition is used for adhesion to a one-component automotive coating;
• and
• wherein said resin component and said isocyanate component react to form an elastomeric composition having a paint adhesion time to the one-component automotive coating of less than 2 minutes.
