| 摘要 |
The invention describes an adhesive formulation specially designed to bond and stick plastic materials with no surface polarity and porosity such as polypropylene and the like, with no need for prior treatment of the surface to be bonded. The formulation essentially consists of a combination based on: amorphous polyolefins; other polymers to give the formulation properties of viscosity, flexibility, cohesion and tensile strength; tackifying resins which provide stickiness; waxes which allow regulation of the solidification speed cf the adhesive, and other additives such as plasticisers and antioxidants, together with an adhesion promoting additive of the malonic acid type. |
