Definitions

• This invention relates to a hardenable (curable) product com ⁇ position consisting of a liquid curable polymer part (prior to curing) and a vulcanized, or cured elastic part in solid form present as a reinforcement or elastic filler of the mix- ture after curing.
• the curable polymer part can preferably consist of a two com ⁇ ponent curable urethane polymer, and the second part, e.g., of a vulcan-zed, natural or synthetic rubber in the form of spherical particles having a diameter, preferably less than about 1 mm, or of fiber form having a length of 5 to 15 mm, and a diameter less than 1 mm.
• the part of vulcanized rubber shall have such an elasticity modulus, and hardness that cor ⁇ respond to the use of the final mixed product.
• the incorporation by mixing of solid particles and/or fibres can be 10 to 40 % by weight of the mixture depending on the properties wanted of the final product. After mixing of the parts, and application, and shaping, respectively, the mix- ture is cured in situ.
• the product composition intended can be used for a number of purposes.
• the composition can be applied on a surface which shall be protected from mechanical damage, e.g., wear- mg surfaces on transport devices.
• the composition can also be sprayed, rolled, apinted, and stopped, or in any other way be applied onto a surface of a material as a protection against corrosion, water, and aggresive liquids.
• the compo ⁇ sition can be cast in a mould prior to curing, e.g., at the production of vehicle tires, and other cast products. Lt can also be used in tightening of tube joints and closures.litis,,, .
• the product composition can be provided with agents that pro ⁇ vide particular properties to the finished composition,..such as colour by adding a colour pigment, increased-adhesiveness by adding a tar fraction, tixotrophy by adding zeolithes. fire restistance by adding organic chloro compounds, and cor ⁇ rosion inhibiting properties by adding inhibitors such as hexamethylene diamine.

• a product composition according to the invention can contain a binding agent for the rubber particles, and fibres, respectively, present, consist ⁇ ing of a mixture of the following components:
• DESMOPHEN 1150 Branched polyalcohol having ether and ester groups present.
• DESMODUR VL Polyisocyanate, prepolymer based on diphenyl methane - diisocyanate. (Viscosity about half of that of DESMO- • PHEN 1150) .
