One-component systems

Polyester-based one-component interlocked polyurethanes cure after exposure to heat (135-140°C). As a one-component product, they do not require mixing, and their main advantage is the low waste level of the system (no risk of incorrect proportions). In addition, these systems are characterised by easy venting and absence of volatile isocyanate vapours (which results from their chemical bonding in the mixture). Available hardness range of one-component systems extends within Shore 20-90.


 

Short processing instruction – MB Resin

MB Resin – heat processing instruction:

  1. Melt MB Resin at a temperature NOT HIGHER than 55°C. If the melted resin has high viscosity and it is difficult to be poured out of the package, the melting temperature can be gradually increased by 5°C; however, 70°C must not be exceeded.
  2. If the molten resin is not homogeneous or it is creamy in colour rather than amber, the mixture has undergone sedimentation. In this case, thoroughly mix the contents of the package using a drilling machine, and store the package upside down after closing.
  3. Coat the mould with an appropriate release agent.
  4. Heat the moulds to 80°C. After pouring the resin into the mould, increase the oven temperature to 110°C for two hours (closed metal moulds are recommended).
  5. MB Resin cures for 16-18 hours at 135-140°C.

Spray systems

Polyurea

Two-component, solvent-free polyurea materials for use at ambient temperature (with 1:1 volume ratio). Thanks to its permanent flexibility, the membrane  provides reinforcement of substrata such as concrete and steel through bridging cracks on their surface.

 

Hybrid

The material can be used for a wide range of substrata at ambient temperature, it is characterized by a high reaction swiftness, which is standard for most spray materials, where the sprayed membrane is dry after a few seconds. The system is designed for use through 1:1 volumetric spraying devices.

Quick processing guide – Duramould

Duramould – processing at room temperature:

  1. Prepare the model: seal the model-box contact line and the box with silicone. Coat the model and the box in which it is placed with a separator.
  2. Before use, polyol should be mixed at slow speed for about 5-10 minutes with a stirrer mounted in a drilling machine, then wait for about 30 minutes to bleed air from the material. Isocyanate does not require mixing.
  3. Place an empty, clean and dry container on the scale; tare the scale.
  4. Weigh out the polyol component. Add the isocyanate component.
  5. Mix using a drilling machine with a tip that does not cause the aeration of the material. Mix at low speed.
  6. Pour the mixture into a clean container, mix again for a few minutes. Bleed air from the material if necessary.
  7. Calmly, pour the material into the model box. Pour a thin stream onto one point, do not pour from a height.
  8. The mould should be removed after 24 hours, after which the mould should be aged on an even plate at room temperature for 48 hours.

Moulding silicone

The silicones available in our offer are two-component, liquid systems cured at room temperature. They are characterized by exceptional tear resistance and great working properties (exceptional anti-adhesive properties and easy unforming / demoulding. They are used, among others, as moulds for: resin, polyester, polyurethane, wax, parget, plaster of Paris, and concrete cast.

 

Instructions for silicones processing

  1. Clean the surface of the material, if necessary (while using porous material) use a release agent: petroleum jelly, or aqueous soap solution.
  2. Mix part A thoroughly before use.
  3. In a clean container, weigh out equal amounts of components A and B. Mix them manually or mechanically (pay attention not to do so for too long, do not exceed the temperature of 35°C in the mixture).
  4. Bleed air from the mixture if necessary.
  5. Pour the mixture onto the original, leave to season for 24 hours at room temperature. Then remove the original from the mould.
  6. The final mechanical parameters of the mould will be obtained after 7 days.

Cold technology

Hyperlast

Hyperlast is a polyether-based polyurethane system. Hyperlast systems for cold processing, apart from displaying hydrolysis resistance, are economical – their components do not require heating before use and enable the application of plastic molds (which will not be applicable for hot technologies).

 

Quick processing guide – Hyperlast Cold technology

Hyperlast – manual cold processing:

  1. Polyol must be mixed before use – roller stirrer or stirrer mounted in a drilling machine.
  2. Weigh out the necessary amounts of polyol and hardener (while using 3-component systems) into a container, and mix.
  3. Weigh out a required amount of pre-polymer into a container, and mix for about 1 min.
  4. Pour the mixture into a clean container, mix again for several seconds.
  5. Place the mixture under vacuum for about 1-2 minutes or until bubbling stops (this step can be skipped depending on the expected visual and qualitative parameters).
  6. Pour the mixed ingredients into a mould previously coated with a separating agent.*

*While using Hyperlast 1052, the mould should be heated to the temperature recommended in the technical data sheet.
