Application-led sample validation

Test with confidence. Convert with clarity.

Our Sample Testing process helps you evaluate HPMC, HEMC, RDP and related construction additives in your real formulation before making a purchasing decision.

01

Benchmark first

Start close to your current product.

02

Validate in use

Test under your real production conditions.

01

Planned Follow-Up

We agree on test timing instead of waiting passively for feedback.

02

Real-World Validation

Performance is evaluated in your formula, materials and process.

03

Low Switching Risk

Sample, trial order and batch validation reduce uncertainty step by step.

04

Technical Collaboration

Complex cases can be reviewed with our technical support team.

A clear path from inquiry to trial order

Your Sample Testing Journey

We do not send a random sample based only on viscosity. We first understand the application, then build a practical validation plan around your current product and target performance.

01

Sample Request

Tell us what you are making

Start with your product application, such as tile adhesive, wall putty, gypsum plaster, EIFS/ETICS, dry mix mortar, self-leveling or daily chemical products.

What helps us prepare faster

  • • Product application and expected performance
  • • Monthly consumption and purchase plan
  • • Company name, delivery address and contact details
02

Requirement Collection

Define the real technical requirement

Our team collects the information that affects performance: material system, dosage, target workability, water retention, open time, sag resistance, bonding strength and other priorities.

Why this matters

The same cellulose ether or RDP grade can perform differently across cement types, gypsum systems, fillers, additives, climate and production methods.

03

Current Product Benchmarking

Start close to what already works

Where possible, we benchmark against your current brand, grade, viscosity, dosage and observed performance. This gives the first test a more realistic starting point.

Useful benchmark details

  • • Current supplier, grade or reference sample
  • • Current dosage and formula conditions
  • • What you want to retain or improve
04

Sample Preparation & Shipment

Select, pack and dispatch the right sample

After an initial product recommendation and commercial alignment, samples are prepared for your selected application and shipped with relevant product information.

Before dispatch

We confirm the sample grade, quantity, delivery contact, shipping method and expected arrival time so your team can prepare for testing.

05

Receipt Confirmation

Confirm the sample has arrived safely

Once the sample is delivered, we confirm receipt, package condition and whether the sample has reached the person responsible for technical evaluation.

A simple but essential checkpoint

This avoids lost samples, unclear internal handovers and unnecessary delays before the testing process begins.

06

Test Planning

Agree on a test plan and evaluation criteria

We clarify when the test will begin, what the benchmark is, which properties will be checked and when feedback can be expected from your laboratory or production team.

Typical evaluation points

  • • Workability, water retention and open time
  • • Sag resistance, strength and surface finish
  • • Dosage efficiency and overall cost-in-use
07

Approx. 28-Day Validation

Allow enough time for meaningful results

Some construction material tests, especially those involving curing and bond strength, may take around 28 days. We schedule milestone follow-ups rather than treating the process as a one-time shipment.

During the validation period

Our sales and technical teams remain available for questions on mixing, dosage adjustments, comparison methods and unexpected observations.

08

Failure Review

A failed test is data, not the end of the project

If the first sample does not meet expectations, we review the specific failure point and compare it with the benchmark, formula conditions, materials, dosage and test method.

What we review together

  • • Which performance result was below target
  • • How the benchmark product performed
  • • Whether formula or grade optimization is needed
09

Second-Round Testing

Optimize, retest and verify improvement

Based on the review, we may recommend an adjusted grade, modified dosage or a more suitable solution. The objective is not simply to repeat the first test, but to improve the next test intelligently.

For complex applications

When the formula or target performance is more demanding, our technical team can join the review to support a more precise recommendation.

10

Trial Order Conversion

Move from sample success to controlled commercial validation

After a successful sample test, a trial order allows you to confirm bulk material performance, packaging, delivery, production consistency and practical use at a larger scale.

The goal: long-term supply confidence

A trial order is the bridge between laboratory approval and stable repeat purchasing. It helps reduce switching risk before supply volume increases.

Testing success starts with better information

What to prepare before your sample test

You do not need to disclose every formula detail immediately. However, the more relevant information we understand, the more accurately we can recommend a starting grade and testing approach.

01

Your Application

Tile adhesive, putty, EIFS, gypsum, dry mix mortar, coating or daily chemical application.

02

Current Product

Current brand, grade, viscosity, dosage and the performance you expect to match or improve.

03

Test Conditions

Key raw materials, test method, project timing and the person responsible for evaluation.

04

Commercial Direction

Expected demand, target market, delivery location and whether you need a second supply source.

Start your evaluation

Request a sample for your application

Share the basics of your project. Our team will review your application and contact you to confirm the most suitable starting point for testing.

1

Application-focused recommendation

We recommend based on your actual use case, not only a single technical number.

2

Clear next steps

We align on sample dispatch, test timing and feedback expectations before the process begins.

3

Support through trial conversion

When testing is successful, we help you move toward a controlled trial order with confidence.
