Arjay Technologies Quality Assurance Guide

Arjay has been involved in the marine industry for over 25 years. Having taken part in both fiberglass component manufacturing and polyester compounding, we are uniquely positioned to offer premium quality - cost competitive products to the marine, transportation, and architectural industries. In order to provide consistent products to our customers Arjay uses a variety of quality control procedures and checkpoints to ensure dependable and repeatable product performance. By monitoring all phases of the manufacturing process, batch to batch consistency is maintained. This outline of the Quality Assurance process is intended to show the general process and not the exact procedures and acceptance values used in determining material suitability.

A. Incoming Material Inspections

A wide variety of raw materials are required to manufacture our products. Generally they may be classified into three distinct categories, consisting of Liquids, Fillers, and Containers.

1. Liquids: Encompass several materials that include: solvents, promoters, initiators and resins. All liquids must be within assurance guidelines to be accepted. Each liquid used by Arjay has a list of specifications that includes density, reactivity, viscosity, and color. Actual values are compared to acceptable ranges - and must be met before the product is approved for use.
2. Fillers: All the fillers used by Arjay are quality controlled based on density, particle size and particle geometry. All fillers have a set of acceptance values that must correspond to the products we receive before being approved for use in production.
3. Containers: All packaging container shipments are visually inspected and solvent resistance checked. In addition, they are pressure tested in accordance with UN specifications and sealed using approved DOT techniques.

B. In Process Inspections

To help ensure manufacture of a consistent and quality batch, each product has multiple inspection points throughout the process. The most important is monitoring the weight of the processing vessel.

1. Weight control: All processing vessels are controlled with digitally monitored load cells to help ensure accurate product delivery.
2. Each product has at least 3 points during processing that critical to quality weights are checked against acceptable ranges. This allows weights to be monitored and adjusted so the final product has greater consistency and repeatability.

C. Product Pre-packaging Inspection

All batches are subjected to several quality assurance tests prior to packaging - and must be within acceptance guidelines in order to be approved for packaging. The critical to quality properties analyzed include: cure dynamics, resistance to flow and mass density.

1. Cure dynamics: This includes gel and cure times as well as exothermal properties.
2. Resistance to flow: Viscosity of the products is measured precisely using a digital viscometer on a heli-path stand. The measured viscosity is reported in centipoise for 2 different RPM values.
3. Mass density: Product test samples are measured with a standard 100 ml stainless steel density cup and reported in lbs per gallon.
4. All batches require quality control approval before packaging and a certificate of analysis must be available on the Arjay network.

D. Product Post-packaging Inspection

Prior to loading products for shipping several final inspections are also performed to ensure the right product is being shipped and that it can arrive intact - in good condition.

1. All products packaged for shipment are checked against acceptable values for container weight as well as proper product identification, hazardous material labels and shelf life date.
2. A standard batch quality assurance certificate of analysis is provide and accompanies the shipping documents.
3. Palletized quantities are inspected for intact containers, adequate strapping and load securement.

While the ultimate test of quality is the repeat business of our customers the parameters outlined here help assure that we can continue to produce the consistent quality products our customers have come to expect.
