Impregnating compounds

Resins for impregnation of wood, concrete and plaster

Q: Which resin is suitable for impregnation of concrete?

For the primary test, a solution of hydrocarbon resin or 5/9 ATP is considered. The choice depends on the solvent, porosity, flow rate and the type of surface required.

Q: Does the film form on concrete?

It depends on concentration, flow and porosity. You need coatings, penetration and appearance.

Film-forming resin solution for impregnating wood, concrete and plaster. Suitability depends on the substrate and solvent system.

What determines the work of impregnation on a porous basis

The same liquid composition behaves differently on wood, dense concrete and porous plaster.

Film-forming semi-finished product for mixing production

An HCR solution is convenient for plants that do not want a separate solid-resin dissolution step. SPS 5/9 may be considered when the manufacturer prepares the solution in-house. In both cases, confirm solvent, non-volatile content and compatibility, then test on the actual substrate.

Production applications

Resin test points

Raw materials for producers of impregnation of wood, concrete and mineral bases.

01 · Wood

Wood-impregnation compounds

The solution is checked on the selected wood species, humidity and surface preparation.

In the test: absorption, uniformity, drying, colour, odour and water

02 · Concrete

Impregnation of concrete bases

Take into account the porosity and humidity of concrete, the depth of penetration and the admissibility of the surface film for the selected type of impregnation.

In the test: flow, penetration, strengthening, appearance and water absorption

03 · Plaster

Mineral and porous surfaces

The resin is tested on the real composition of the plaster and the accepted method of application.

In the test: absorption, spotting, adhesion of subsequent layers and drying

04 · Production

Blending without separate dissolution

The finished solution can shorten the operation if its solvent and concentration fit the material balance.

In the test: dosing, mixing, filtration, storage and dry matter cost

Primary list

NPS solution and copolymer resin

Compare the composition and purpose of products. SPS 5/9 and an HCR solution may differ in resin base, not only in supply form.

Monitoring

What to test in the impregnation and substrate

Compare on actual substrates with controlled preparation and moisture.

Phase	What to measure	Comparison condition
Semi-finished	Solvent, non-volatile, viscosity, homogeneity	Batch CoA
Application	Method, consumption, wetting	With identical preparation
Penetration	Depth and uniformity	By cut or accepted method
Drying	Tack-free time, odour after conditioning, tack	In a given climate.
Surface.	Colour, gloss, mottling, film	Material requirements
The effect	Water absorption, strengthening, subsequent layers	On the finished substrate

For a resin solution, compare cost by contained resin mass, including solvent, delivery and the eliminated dissolution step.

Qualification

Selecting an impregnation intermediate

First, the liquid system is agreed, then a test series is run on the actual substrate.

Describe the basis

Material, porosity, humidity, preparation and method of application.

Verify solution

Solvent, non-volatile substances, viscosity and certificate of analysis for the batch.

Application test

The control and trial formulations are compared by the same consumption and exposure.

Check the effect

Evaluate penetration, drying, appearance, water resistance and a pilot batch.

Boundaries of application

When the resin solution is unsuitable

If its solvent base is incompatible with the formulation or production requirements.
If the substrate does not permit colour change, gloss or a surface film.
If the price is compared with solid resin without counting for non-volatile substances.
If it is not possible to check the real base, humidity, flow rate and drying.

FAQ

Technical and purchasing questions

Purpose of resins, selection criteria and preparation of samples.

Which resin is suitable for impregnation of concrete?

For the primary test, a solution of hydrocarbon resin or SPS 5/9 is considered. The choice depends on the solvent, porosity, flow rate and the type of surface required.

Is it possible to use NPS solution for wood?

Yes, wood is included in confirmed directions, but the composition is tested on a specific rock and humidity for absorption, drying, colour and water resistance.

Which is more profitable: solution or solid resin?

Compare the cost per mass of non-volatile resin, solvent, delivery, energy costs, losses and self-dissolution time.

What solvent is contained in the solution of NPS?

The composition of the solvent should be obtained in the technical description of the selected product before calculating the concentration and dosage.

Does the film form on concrete?

It depends on concentration, flow and porosity. Check coating formation, penetration and appearance.

What to send for selection?
